Why does my MCUK smell?

Your MCUK shouldn’t normally have a strong odor. The most common reasons for a menstrual cup developing an odor are:

  • leaving the cup in a lot longer than the advised 4 to 8 hours; or
  • boiling the cup in a saucepan that may have had traces of food left on the surface.

If this is not the case, you may have a non-serious vaginal infection that should be checked out by your doctor or nurse.

Removing odor from your MCUK

To remove the odor:

  1. Soak your menstrual cup in a small container of sterilizing solution such as that used for sterilizing baby bottle teats diluted to the manufacturer’s guidelines for the minimum recommended time (usually 7 to 10 minutes).
  2. Rinse thoroughly with clean water.
